Variant information Variant position:

165 The position of the amino-acid change on the UniProtKB canonical protein sequence.
Type of variant:

LB/B The variants are classified into three categories: LP/P, LB/B and US.

LP/P: likely pathogenic or pathogenic.
LB/B: likely benign or benign.
US: uncertain significance

Residue change:

From Glycine (G) to Aspartate (D) at position 165 (G165D, p.Gly165Asp). Indicates the amino acid change of the variant. The one-letter and three-letter codes for amino acids used in UniProtKB/Swiss-Prot are those adopted by the commission on Biochemical Nomenclature of the IUPAC-IUB.
Physico-chemical properties:

Change from glycine (G) to medium size and acidic (D) The physico-chemical property of the reference and variant residues and the change implicated.
BLOSUM score:

-1 The score within a Blosum matrix for the corresponding wild-type to variant amino acid change. The log-odds score measures the logarithm for the ratio of the likelihood of two amino acids appearing by chance. The Blosum62 substitution matrix is used. This substitution matrix contains scores for all possible exchanges of one amino acid with another:

Lowest score: -4 (low probability of substitution).
Highest score: 11 (high probability of substitution).

Polymorphism:

AQP1 is responsible for the Colton blood group system [MIM:110450]. Approximately 92% of Caucasians are Co(A+B-) (Ala-45), approximately 8% are Co(A+B+), and only 0.2% are Co(A-B+) (Val-45). Co(A-B-) which is very rare, is due to a complete absence of AQP1. Additional information on the polymorphism described.
